什么样的提问课堂问答活动是必须的、必要的、能促进学生语言表达和思维发展的？笔者经过多年的课堂观察，结合自己教学实践，认为无论何种问题、何种方式，学生的表达应为教学的核心。下面笔者结合具体的案例，谈一谈对此浅显的认识。

Then and now是译林新版《英语》六年级上册Unit 4 Story time板块的内容，主要知识点是关于过去和现在的对比，涉及到一些有关购物、联络、读书等生活方式的改变。在对文本解读时，教师往往会根据文本的四个部分，提出不同的问题来捕捉细节信息，按部就班、逐段学习。笔者在教学时没有受文本框架的限制，而是通过一个Guessing game，说明第二至第四部分中有关购物、联络、读书等生活方式的转变与Mobile phone之间的联系，先行解决阅读障碍，再进行文本精读。笔者设计了以下活动：

T:I have a good friend.I can do many thingswith it.Twenty yearsago,Idid not have it.Now I use it everyday.What is it?

S1:Is it a computer?

T:It’ssmallerthan the computer.

S2:Is it a mobile?

T:Yes,it’s a mobile phone.I can do many things with it.What can I do with it?

S3:You can read.

S4:You can shop.

S5:You can call.

T:Yes.I can call people anywhere.Anything else?

S6: You can surf the Internet.

S7:You can read.

T:Right.I can read news and novels on the mobile.The mobile is just like an e-book.

...

（相机学习mobile phone,anywhere,news,e-books）

设计意图：文本中提到人们生活方式的变化与手机、电子书、电脑、网络有关，但逐一对应地讲解将使课堂节奏显得冗长而繁琐。教师借助谜语，将智能手机的联络、网上购物、游戏、阅读等功能一一呈现，为学生进一步精读文本做好了语言上的准备。

T:Mobile is changing our life.How about Mike’s family?Now listen to the tape and find who are in the story.Open your exercise book and finish exercise 1 on P37.（见图 a）

T:Look at this picture.（教师出示图 b）He is Mike.Now,he is a young boy.Let’s guess,what can he do?

S1:He can play football.

S2:He can sing.

S3:He can write.

S4:He can do housework....

T:Now he can do...

Ss:...many things.（教师板书“can do many things”）

T:Look atthis picture.（教师出示图 c）Who is he?Guess.

S5:Is he Mike?

T:He was Mike six years ago.Could Mike do all these things six years ago? What could he do?Now listen to the tape and find the answer.

S6:Mike could read.

S7:Mike could draw.

T:Could he write?

S8:No.He could not write.

（教师出示表格，学生完成填空）

Name Six years ago Now Mike could read and draw,couldn’t write can do many things

设计意图：教师抛出的问题并不多，但学生有话可说。通过图b和图c的对比，发挥学生的想象力，在“Mike can...”句式操练中，自然总结出：He can do many things.有效促进知识的内化和迁移。

T:Mike couldn’t write six years ago.Now he can write.He can do many things.Mike’s then and now are different.How about other people?What changes to their life? Read passage 2-4 and discuss in groups.

学生小组合作，完成关于Mike’s Dad/Mum/Grandpa 三个部分的学习。学生根据文本内容自行设计问……
